Name: Cat Blood Test Reference Ranges — Every Value Sourced
Creator: Marcin Siedlecki
License: https://vetblood.io/about/

Evidence-based veterinary medicine (EBVM) only. Every value on this page carries a named source.

All 155 values on this page are traced to a named source. Every sourced entry is traced to a named laboratory reference document, an established veterinary clinical pathology reference, or peer-reviewed literature — hover it to see where it came from. We never fill a gap by analogy with a related species.

Reference intervals for the cat — biochemistry, haematology, urinalysis and specialised tests, in one place, with the provenance of every value stated.

Take the data with you. Every row carries the value and the source it came from, so each number can be checked at its origin without coming back here. Free to reuse with attribution.

Read this before you use the table. Reference intervals are analyser- and method-dependent. The interval printed on your own laboratory report always takes precedence over any published table, including this one. These figures are for orientation and teaching. They are not a diagnosis and do not replace examination by a veterinarian.

What kind of proof stands behind each number

Hover any value to see its source and how to check it. The symbol tells you what kind of evidence it is.

Method

Evidence-based veterinary medicine (EBVM) only. This page follows the principles of evidence-based veterinary medicine: every value is traceable to a named source, and where the evidence does not exist we say so. A value appears here solely when it can be traced to a named source: a laboratory reference document, an established veterinary clinical pathology reference, or peer-reviewed literature. There is no category of “commonly quoted” or “textbook approximate” value on this site.

Gaps stay gaps. Where an interval has not been established, the entry is absent. We do not substitute a value from a related species and we do not average across sources. 0 values held internally are withheld from these pages because their provenance is not recorded.

One dataset. Every number here is the number our articles use, with the same source attached.

Derived values are labelled. Where an interval was calculated from a published mean and standard deviation rather than formally established, the source entry says so explicitly.
